前言
采用Anemometer将Mysql慢查询日志可视化,可以更便捷的查询慢查询日志,并根据时间戳进行历史查询。如下是单机版Anemometer部署的演示,实际应用中,为安全起见,建议把anemometer 分开到另外的机器上。
工作原理
Anemometer: 实现日志可视化
pt-query-digest :抽取慢查询日志
环境信息
Ip | 功能 | 软件信息 | 安装路径 | 操作系统 |
192.168.9.11 | http服务 | httpd-2.2.15-54 | yum缺省路径 | centos6.9 |
慢查询日志抓取导入 | pt-query-digest | rpm缺省路径 | ||
慢查询日志切割 | logrotate | yum缺省路径 | ||
可视化展示 | Anemometer | /var/www/html |
安装步骤
1.安装apache
yum install httpd -y
2.安装pt-query-digest并设置抓取脚本
yum install perl-DBI perl-DBD-MySQL perl-Time-HiRes perl-IO-Socket-SSL -y #需要安装perl-TermReadKey否则会报错 wget http://pkgs.repoforge.org/perl-TermReadKey/perl-TermReadKey-2.30-1.el3.rf.x86_64.rpm rpm -ivh perl-TermReadKey-2.30-1.el3.rf.x86_64.rpm wget https://www.percona.com/downloads/percona-toolkit/2.2.20/RPM/percona-toolkit-2.2.20-1.noarch.rpm rpm -ivh percona-toolkit-2.2.20-1.noarch.rpm vim /home/shell_script/slow_db_export.sh #!/bin/bash /usr/bin/pt-query-digest --user=anemometer --password=123456 --review h=192.168.9.11,D=slow_query_log,t=global_query_review --history h=192.168.9.11, D=slow_query_log,t=global_query_review_history --no-report --limit=0% --filter=" \$event->{Bytes} = length(\$event->{arg}) and \$event->{hostname}=\"$HOSTNAME\"" /usr/local/mysql/data/mysql.slow chmod -R 755 /home/shell_script/slow_db_export.sh
3.安装logrotate并配置每日切割mysql慢查询日志
yum install logrotate -y vim /etc/logrotate.d/mysql /usr/local/mysql/data/mysql.slow { create 660 mysql mysql dateext notifempty daily maxage 60 rotate 30 missingok compress olddir /usr/local/mysql/old_log postrotate ##########run if mysqld is running if /usr/local/mysql/bin/mysqladmin ping -h172.27.127.12 -uroot -p‘Hs!hs8989‘ -S /usr/local/mysql/mysql.sock &>/dev/null; then /usr/local/mysql/bin/mysqladmin flush-logs -h172.27.127.12 -uroot -p‘Hs!hs8989‘ -S /usr/local/mysql/mysql.sock fi endscript } chmod -R 755 /etc/logrotate.d/mysql
4.将pt-query-digest脚本和logrotate切割脚本放入crontab中
#############23点55分-分割导入当天的慢查询数据##################### 55 23 * * * /home/shell_script/slow_db_export.sh ###############23点59分-切割慢查询日志############# 59 23 * * * root ( /usr/sbin/logrotate -f /etc/logrotate.d/mysql)
5.安装Anemometer
cd /var/www/html git clone https://github.com/box/Anemometer.git anemometer&&cd anemometer #创建表和用户名 # mysql -uroot -proot < install.sql # mysql-uroot -proot -e "grant ALL ON slow_query_log.* to ‘anemometer‘@‘localhost‘ IDENTIFIED BY ‘123456‘;" # mysql -uroot -proot -e "grant SELECT ON *.* to ‘anemometer‘@‘localhost‘ IDENTIFIED BY ‘123456‘;" # mysql -uroot -proot -e "flush privileges;"
6.导入日志并打开页面测试(http://192.168.9.11/amemometer
#执行刚刚编辑的slow_db_export.sh脚本 ./home/shell_script/slow_db_export.sh #重启apache service httpd restart
至此,已经通过Anemometer实现了mysql慢查询日志可视化功能。
